BABY-CARRIAG E.

SPECIFICATION forming part of Letters Patent No. 495,476, dated April18, 1893.

Application filed September 26, 1892. Serial No, 446,861. (No model.)

To all whom it may concern.-

Be it known that we, JOSEPH DIETRICH and LOUIS HABIOHT, citizens of theUnited States, residing at Buffalo, in the county of Erie and State ofNew York, haveinvented certain new and useful Improvements inBaby-Carriages, of which the following is a specification.

Our invention relates to certain improvements in baby carriages, andwill be fully and clearly hereinafter described and claimed, referencebeing had to the accompanying drawings, in which:-

Figure 1, is a side elevation of a baby carriage, showing our inventionconnected there with, the near side wheels being omitted so as to showthe parts beyond it more clearly. Fig. 2 is a detached side elevation ofone of the springs by which the body of the carriage is supported. Fig.3 is also a detached side elevation of one of the springs, showing oneof the corrugated or toothed disks attached to it. Fig. 4, is anenlarged detached side elevation of the adjustable spring holdingdevice, some portions of it being in section so as to show theconstruction more clearly. Fig. 5 is an enlarged detached side elevationin section for showing the spiral spring for keeping the disks apartwhen the thumb screw is loosened for the purpose of adjusting them. Fig.6 is an enlarged front elevation of one of the corrugated or tootheddisks, showing the socketfor holding one end of the spiral spring forkeeping the two disks apart when the thumb-screw is loosened for thepurpose of adjusting them to raise or lower one end of the body of thecarriage.

Referring to the drawings, 1 represents the body of a carriage. We haveshown in the drawings a willow work carriage body of ordinaryconstruction, as a suitable means for illustrating our invention, butthe carriage body may be constructed in any well known way. The objectof our invention being to construct the springs which support the bodyof the carriage so as to be easily and convenientlyadjustable, wherebythe back end of the body of the carriage may be raised or lowered so asto adapt it to carry different Weights. That is, when the carriage bodyis raised it will require more weight to bring it down to a horizontalor level position or substantially so than it would if adjusted to alower position.

The side frame pieces, 2, are secured to the axles in the usual mannerand are joined at the upper ends, 3, to form the pushing bar. To theseside frame pieces are secured the axles carrying the wheels, 4:. At theforward end of the carriage is secured at the top of each side framepiece, an adjustable spring holding device. These spring holding devicesare rigidly secured to the side bars by means of the clip bolts 5,(shown in Figs. 1 and 4.)

The springs, 6, as will be seen by reference to Figs. 2 and 3, are madein the form of a scroll or a volute and the inner ends are formed into asquare, 7, (see Fig. 2) so that the square shank, or holding piece 8 canpass into it and be held so that it cannot be turned therein. Thisadjustable holding piece is more plainly shown in Fig. 4. It consists ofa base portion, 9, adapted to be secured at the front of the carriage bythe clip bolts, 5, to the side bars one on each side. To the baseportion, 9, is a vertical portion terminating in a disk, 10, having acorrugated face, 11. On the face of the corrugated portion, 11, is adisk, 12, having a corresponding series of corrugations so that one fitsinto the other. Projecting out from the corrugated circular disk, 12, isa square shank, 8, (shown in section in Fig. 4.) This square shank, 8,is adapted to pass through the square hole, 7, of the spring, and isprovided with a longitudinal hole through which a bolt, 14;, is passed,on this bolt, 14., is placed another disk 15, and the whole is rigidlysecured by a thumb-nut, 16. The springs are secured by bolts, 17, to theunder side of the front portion of the body of the carriage so as to beheld thereto.

From the above description it will be seen that by loosening the thumbnuts, 16, so that the corrugated disks may be separated a short distanceapart (by the spiral spring,20, which fits in the sockets 21 and 22between them) so that one may be turned past the other, the body of thecarriage may be turned up to any angle required and the thumb nut againscrewed up tight so that the carriage body is held rigidly in theposition in which it may be adjusted, see dotted lines, 19, in Fig. 1.

Two of the springs, 6, are generally used on a carriage one on eachside, but one, or more springs may be used if desired. These springsshould be made sufficiently strong to support the body of the carriagewith one or two children in it. It will be noticed that for one childthe adjustment of the spring should be different when two are to becarried. The hole, 7, in the spring may if desired be made round withthe end of the spring projecting so as to project into a groove in thesleeve, 8, which in this case should be made round instead of square orthe shank 8 may be round and provided with a projecting lug or feather,or it may be made in any Well known way to prevent it from turning inits corresponding openings in the spring.

We claim as our invention- 1. A baby carriage provided with curvedsprings at the front of the body having their lower ends rigidly securedto the shank of a corrugated disk so they cannot turn thereon,

a holding correspondingly corrugated disk secured at the base by clipbolts to the side bars of the carriage, and a thumb nut for each springby which the body of the carriage and its springs are adjusted at anyangle desired and rigidly secured substantially as described.

2. An adjustable carriage spring, consisting of a scroll shaped spring,6, having its inner end terminate in one irregular shaped hole, 5, incombination with a supporting disk having clip bolts for securing it tothe side bars of a carriage the disk being provided with a series ofteeth or corrugations on one face, a disk having a corresponding seriesof teeth or corrugations and a shank projecting from it adapted to fitthe hole in the spring so it cannot turn therein, and abolt and screwnut for securing the whole to the spring, substantially as described.
